Earth heightmap

prusaprinters

<p>My attempt at height mapping on a sphere. This uses a tetrahedron or icosahedron as base which is recursively mapped to a sphere. This does take some amount of memory &amp; time for nriter&gt;=5.</p> <p>If anyone is interested in making their own openscad heightmap array, use the bash script make_map.sh. Convert the height map into an 8 bit grey scale pgm file with GIMP. Edit "file=new_heightmap.pgm" in make_map.sh to point to the correct image file. Usage:</p> <p>./make_map.sh &gt; map.scad Remove the last comma on the second last line. Add this to to the main scad file with "include " &amp; comment out the current include statement. Adjust the scale (sc) to taste.</p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Monoprice</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>Select Mini</p></div><strong>Rafts:</strong></p> <p>Doesn't Matter</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div><strong>Resolution:</strong></p> <p>0.175</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>10</p></div><br/> <strong>Filament:</strong><br/> Hatchbox PLA </p> </p></p></p> Category: Math Art
